PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 379,958. dated March 27, 1888.

' Application filed February 11', 1887.

- Beit known that I, JOHN M. J ONES, of Palmyra, in the county-of Wayne and State of New York, have invented certain new'and useful Improvements in Printing-Presses, of which the following is a specification. My invention relates, to printingpressesand has reference more particularly to that class of presses in which the bed and platen both move toward each other, although the improvements are applicable to other classes of presses. I

In the drawings, Figure 1 is a side elevaplied thereto; Fig. 2, a vertical central section of the same; Fig. 3, a section on the line a; :0 of Fig. 2; Fig. 4, a top plan view; Figs. 5 and 6-, perspective views of the plates which form the roller-bearings, and Figs. 7 and 8 views illustrating certain details.

A indicates a substantial framing. B the platen, and O the movable bed, all of which parts may be of usual construction, and in the framing A is driving-shaft D. which serves to impart the necessary movements to the platen, bed, and inking-rollers.

In order to throw off or vary the impression I adopt the construction shown in-Figs. 1, 4, and 8, upon reference to which figures it will be seen that the shaft E, journaled in the side plates of bed 0, is provided at its ends with eccentric-journals a, to oneof which is. secured aradial arm, b. This arm is" jointed at its outer end to an upright bar or rod, 0, or to sleeved thereon, as-shown in Figs. 1 and 8, said rod 0 being connected at its lower end with one arm, e, of an elbowlever, .F, pivoted upon afixed stud projecting from the side of frame A, as indicated in Fig. 1. The other arm,f, of this elbow-lever extends upward alongside the frame, and at its upper end is fashioned intoor provided with ahandle, and passes through a loop or guide, g, secured tothe frame, the loop or guide being provided at each end with a recess in its sidewall, into which the handle may spring tolretain the lever in any desired position. It will be seen upon reference to Fig. 1 that as the elbow-lever F is rocked upon its pivot, acting through the rod 0 and arm b, it rocks theshaft E in its bearings in the bed. As the pitmau G, connecting the driving-shaft D with the shaft E, are journaled upon the eccentric portions of the latter, the throw of the pitmen Serial No. 227,soa. (No model.)

ished as shaft E is rotated in one or the other directions.

In order to vary the degree of rotation I provide the rod 0 with an adjustable sleeve,d,

will be variedthat is, increased or dimin- 5 to which I pivotally connect the radial arm 12. V

Screwing into the upper end of rods 0 is a' stem, h, which is provided at its upper end with .a lateral flange, t, and'enlarged head j, and near its lower end with a collar, k, as

shown in Figs. 1 and 8. Sleeve (1 rests at its lower end upon this collar,'and asthe stem h is screwed out of the rod 0 the sleeve rises with the stem. At its upper end the'sleeve d is advisably provided with a lateral flange to fit beneath and against the flanged, and on one side ,of the sleeve there is formed a socket, Z, in which is placed a pointed pin, m, which is urged upward by a spring, n, in the bottom of the socket. The'pointedend of the pin menters one or another of a series of concavities or sockets, o, in the under face of the flange t, as shown in Fig. 8, and is held in engagement therewith by the spring n.

' It will be seen'that as the stem h is screwed into or out of the rod 0 the distance between the points where the elbow-leverF and radial arm I) connect with the rod 0 will be increased .or'diminished, and therefore the throw of the elbow-lever will be correspondingly'changed.

Upon the side of the frame A, a little below and to one side of the shaft H, I, secure a bracket, 10, (shown in Fig. 1,) which is adapted to receive horizontal arm 6 of the elbow-lever F when the upper end of the latter is thrown forward to throw the impression on.

the shaft H are in the samehorizontal plane, and when the arm E of the elbow-lever F rests upon the bracket 1) the pivotal point of connection between the arm e and the rod 0 will 9 It will go be noticed that the'pivot of elbow-lever F and In order that the inking-rollers may be pre vented from passing back and forthover the form I employ adjustable roller bearers or guide-plates I I, and apply said plates or bearers to the sides-of themovable bed, asshown in Figs. 1, 2, 3, and 4, arranging them in such 1 manner that when they are projected beyond the front edges of the bed-frame the journals or shafts of the inking-rollers will move over and upon the edges of said plates or bearers instead of over the front edges of the bedframe. This adjustment will of course raise the inking-rollers so far away from the face of the bed as to prevent them from inking the form. When the bearers or plates are retracted, so that their edges will be in line with or in rear of the front edges of the bed-frame, the inking-rollers will then be allowed to move upon said front edges and ink the form. For the purpose of moving said plates I back and forth I employ the same operating-lever that is employed for changing the impression, and it will be noticed that by this arrangement whenever the impression is thrown off the plates will be projected outward, so as to prevent the inking rollers from touching the form.

Upon reference to Figs. 1, 2, 3, and 5 it will be noticed that the plates I I are provided near their front edges with guide-slots r r, to receive blocks or lugs .51 8, formed upon or secured to the side plates of the bed 0. The plates I I are each provided with a slot, t, to receive a stud, u, on, the side plates of the bed, and are further provided with a large guideslot, 1;, which receives a boss or enlargement, 10, formed upon the side plates of frame 0, as shown in Fig. 3. The walls of the slots or openings 7' r and t are countersunk or beveled on their outer faces, as shown in Figs. 3 and 5, so that the blocks which work in said slots may serve not only to guide the plates, but also confine them to the bed'frame.

Upon the shaft E, just inside the sides of the bed-frame, are secured collars J, as shown in Figs. 2, 3, 4, and 7, each collar being provided with a rigid arm, K, hearing at its end an anti-friction roller, L. This roller, or, in case the roller be omitted, the arm K itself, works between two raised flanges, M and IT, upon the inner face ofeach plate I, as shown in Figs. 2, 3, and 4.

When the upper end of hand lever F is thrown forward to throw the impression on, the shaftE is rocked in such direction as to cause the arm Kto rise, and in thus rising it strikes against the flange N on plate I, and, owing to the inclination of the said flange,this movement of the arm against the latter causes the plates to move back until their front edges are back-of or on line with the sides of the bed-frame. When the hand-lever F is moved to the position shown in Fig. 1 to throw the impression off, the shaft E is rocked in the reverse direction-that is to say, it is rocked so as to throw the free end of the arm K downward. In thus moving downward the arm K strikes against the lower end or tail of the flangeor lug M and causes the plates or bearers I- I to project beyond the front edge of the bed-frame.

I do not claim, broadly, the application of movable plates or bearers to a press for the purpose of preventing the rollers from touching the form, as Iam aware that such a device has been patented. As shown in Figs. 1, 2, and 4, the shaft E is provided with a lug or cam, av, about midway between its ends, and against this lug bears the lower end of an arm or lever, O, pivoted at a point between its ends to the ink-table framing or support. At its upper end the lever O is provided with an ink-fountain, P, of any suit-able construction, and it will be seen that as the-shaft E is rocked in its bearings, so as to throw the impression 011 and advance the plates or' bearers I I, the lug w on the shaft will bear against and throw the lower end of lever O outward. This movement of the lever throws the ink-fountain P down in proper position to feed the ink to the ink-table or rollers. A spring, 31, is connected with the lever 0, so as to return the lever and its fountain P to their normal positions.

Q indicates one of the ink-roller carriages, which is mounted upon the shaft E, as is usual, and which is provided with spring-actuated rods R R, carrying at their upper ends blocks or downwardly-extending arm secured to the gripper rod or shaft and advisably provided with afriction-roller at its lower end. Upon the frame of the machine is a block, V, (shown in Figs. 1 and 4,) having a substantially-upright rear face, upon which face the lower end of the arm U travels, as the platen moves toward and away from the bed.

A spring, a, connects the grippers or gripper-shaft with the platen in such manner as to exert a constant tendency to hold the grippers in an upright position. As the platen is rocked upon its shaft, the arm U- on its roller rides down the upright face of block V, placing the spring a under increasing tension or strain until the arm or roller reaches the lower face of the block. After the impression has been made the platen swings or oscillates backward upon the shaft and the arm U ridesup the upright face of the block V. The spring a and the bearing-faces of the block V are so arranged that when the platen reaches the limit of its backward movement, as in Fi 1, the grippers will be substantially vertical. The block V and arm U prevent the spring a from throwing the gripper too far toward the bed, and also cause the grippers to fall down upon the platen as the latter-is rocked.

The feeding-table-W is provided at one corner with a socket, X, which receives antarm,

Y, secured to the right-hand feed-board, Z, as

shown in Fig. 4. It will be noticed that the arm Y, instead of projecting outward over the 379,958 I a e I claim is 1.
